白内障患者手术后干眼不应忽视

白内障患者手术后发生干眼的问题已经引起了国内外学者的注意.白内障患者术后干眼可分为早期(可逆性)干眼和慢性(不可逆性)干眼,前者术前泪液分泌功能多为正常,由于手术及术后用药等因素的影响,术后泪液分泌暂时性减少,随着相关因素的去除,其功能可以恢复正常;后者术前已患有干眼,或泪液分泌功能处于"边界状态",手术及术后相关因素加剧了泪液分泌的异常,甚至造成眼表组织的异常.及时发现和正确处理术后干眼,对维持眼表稳定性和更好地恢复视力均有重要的临床意义.

Not to ignore the dry eye of cataract patients after surgery

Dry eye syndrome following cataract surgery was concerned about recently. Two kinds of dry eye were clinically observed after cataract surgery, early dry eye and chronic dry eye. Most cases of early dry eye, who usually had the normal lacrimal secretion before surgery, were reversible and involved in some of factors associated with surgery and post-surgery medication. But most cases of chronic dry eye, who have abnormal lacrimal secretion or "borderline state" of lacrimal secretion test before surgery, may suffer from the ocular surface diseases related to irreversible dry eye disease. It is significantly important for maintaining of the ocular surface stability and recovery of vision acuity after cataract surgery to do early diagnose and promptly manage the dry eye syndrome.
